Introduction

A deficient abductor mechanism leads to significant morbidity and few studies have been published describing methods for reconstruction or repair. This study reports the reconstruction of hip abductor deficiency using human allograft.

Methods

All patients were identified as having deficient abductor mechanisms following total hip arthroplasty through radiographic assessment, MRI, clinical examination and intra-operative exploration. All patients underwent hip abductor reconstruction using a variety of human allografts including proximal humeral, tensor fascia lata, quadriceps and patellar tendon.

The type of allograft reconstruction used was customized to each patient, all being attached to proximal femur, allograft bone adjacent to host bone, with cerclage wires. If a mid-substance muscle rupture was identified an allograft tendon to host tendon reconstruction was performed.

Introduction

Revision hip arthroplasty with massive proximal femoral bone loss remains challenging. Whilst several surgical techniques have been described, few have reported long term supporting data. A proximal femoral allograft (PFA) may be used to reconstitute bone stock in the multiply revised femur with segmental bone loss of greater than 8 cm. This study reports the outcome of largest case series of PFA used in revision hip arthroplasty.

Methods

Data was prospectively collected from a consecutive series of 69 revision hip cases incorporating PFA and retrospective analyzed. Allografts of greater than 8 cm in length (average 14cm) implanted to replace deficient bone stock during revision hip surgery between 1984 and 2000 were included. The average age at surgery was 56 years (range 32–84) with a minimum follow up of 10 years and a mean of 15.8 years (range).

In order to determine the effectiveness of part-time bracing in juvenile idiopathic scoliosis (JIS) a retrospective review of thirty-four patients treated with a Charleston bending brace for JIS was undertaken. The patients were analyzed in three groups including:

success;

progression;

progression requiring surgery.

Of twenty-three patients meeting the inclusion criteria, nine achieved success, seven progressed, and seven required surgery. Success correlated with best in brace correction radiograph but not with initial curve magnitude. Part-time bracing is as successful as full-time bracing in JIS and better than the natural history.

In order to determine the effectiveness of part-time bracing in JIS, a retrospective review of thirty-four patients treated with a Charleston bending brace for JIS was undertaken.

Twenty-three patients met the inclusion criteria which included: curves greater than twenty degrees at initiation of bracing, Risser zero, bracewear more than twelve months, completion of the bracing program and Risser greater than or equal to four at final follow-up. Patients were analyzed in three groups, including

success (progression less than five degrees or less);

progression more than five degrees (but not requiring surgery) and

progression requiring surgery.

There were seven boys and sixteen girls with thirty-seven curves analyzed. Age at referral averaged 8.3 years. Average curve at time of bracing was thiry degrees. Length of bracing averaged 4.2 years with follow-up averaging 6.2 years. Nine patients met the criteria for success with seven patients progressing and seven patients requiring surgery. Of all curves, nineteen (51%) were successfully managed in the brace. Magnitude of curvature at initiation of bracing was not related to ultimate success, whereas success did correlate with higher best in brace correction radiographs.

Part-time bracing offers potential psychosocial and compliance benefits considering the length of treatment necessary in patients with juvenile idiopathic scoliosis. Although previous bracing studies have included some JIS patients, no authors have dealt specifically with the part-time bracing for JIS.

Part-time bracing is as successful as full-time bracing in JIS and better than the natural history.
